CASH REGI S TER AND INDICATOR.

SPECIFICATION forming part of Letters Patent No. 489,382, dated January 3, 1893.

Application filed October 9, 1890. Renewed October 7, 1891. Serial No. 407,985. (No model.)

To all whom it may concern.-

Be it known that I, MELVIN N. LOVELL, a citizen of the United States, residing at Erie, in the county of Erie and State of Pennsylvania, have invented certain new and useful Improvements in Cash Registering and Indicating Machines; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to cash registering and indicating machines, and consists in certain improvements in the construction thereof as will be hereinafter fully set forth and pointed out in the claims.

The invention is illustrated in the accompanying drawings as follows:Figure 1,is a plan View of the working parts of the machine with certain duplicated parts omitted and others broken away so as to show construction of parts beyond. Fig. 2,is a longitudinal, vertical section on the line Z, Z, in Figf l, with the working parts generally in elevation and with certain duplicated parts omitted and other parts broken away so as to show the construction of parts beyond. Fig. 3,-is a transverse vertical section taken on the line y-y in Fig. 1, with the working parts generally in elevation. Fig. 4,is a like view to that in Fig. 3, and shows a modification in the construction. Fig. 5,is a transverse, sectional view taken on the line m, w, in Fig. 1, and shows the same construction as is shown in Fig. 4. The difference between the View shown in Fig. 4; and that shown in Fig. 5 is that in Fig. 4 the key lever is shown depressed and the tablet up and the drawer is open while in Fig. 5 the key is up,

the tablet down and the drawer is closed. In Fig. 3 the same position of parts is shown as in Fig. &. Fig. 6,-a side elevation of one of the primary register wheels. Fig. 7,-is an edge elevation of the same wheel. Fig. 8, is a side elevation of one of the secondary register wheels. Fig. 9,is an edge elevation of the same wheel. Fig. 10,is a front view of one of the tablet rods as used in the construction shown in Figs. 2, 4 and 5.

is a like view of the same part as used in the construction shown in Fig. 3.

Fig. 11,-

One of the objects of my invention is to enable me to use wood for nearly all the parts of the machine, and this, together with the extreme simplicity of the construction, enables me to make a highly serviceable machine at very small cost.

The machine may have as many keys, tablets and registering wheels as desired, but, as shown, as few of these parts are used as will suflice to accomplish the indication of all amounts up to ten dollars and the registering of all amounts indicated. The keys used, as shown, are: a blank, or, as marked, a O-key. The tablet rod of this key, as shown, has no tablet on it but it may have a tablet with any mark desired, such as Drawer, ticket, check, &c. The office of this key is to open the drawer and operate the releasing devices whereby the tablet rods that are up are released and allowed to drop. There is, of course, no register wheel connected with this key. The other keys are as follows:- one cent, two cents, three cents, five cents, ten cents, fifteen cents, twenty-five cents, fifty cents, one dollar, two dollars, three dollars, five dollars,

To indicate four cents the three cent and one cent keys are depressed. To indicate seven cents the five and two cent keys may be depressed. To indicate ten dollars the five, three and two dollar keys may be used. Other amounts not represented by a single key may be similarly indicated.

All the keys except the O-key are made to operate upon a separate primary register wheel and each primary wheel is consorted with a secondary register wheel which is moved one degree as the primary wheel is-moved a complete revolution.

I make the wheels large and divide them into thirty spaces, therefore each primary wheel will register thirty indications when it has made one complete revolution and the secondary wheel will register nine hundred indications when it has made a complete revolution. To ascertain the total amountthat has been indicated by all the tablets. it is necessary to add together the amounts which are opposite the reading bar on all the wheels.

The method of using the machineisas follows: First depress the O-key, this will cause ICO the drawer to open and the displayed tablets to drop out of sight; then depress the proper numbered keys and close the drawer. lVhen it is wanted to know the total sum received, open the case and add up the column of figures along the side of the reading bar.

From the above general description o the construction and operation of the machine the following description of the details of construction and operation will be easily understood.

A, marks the case of the machine; A, the lid or cover.

a, a, a and a are parts of the frame work.

B, is the drawer; B, the spring by which the drawer is pushed open.

O, are the keys, or key-levers, and will be spoken of herein as keys.

D, marks the primary register wheels and D, the secondary register wheels.

(1 and d are ratchet pins on the sides of the respective register wheels.

F, marks the tablet rods and F, the tablets.

G, is a grooved board or frame piece on the back of the case, in the grooves of which the tablet rods move; G, is a like grooved piece which sets in the front of the piece G, and has its grooves register with those of the board G, so that short tubular spaces are formed. H, are pawls or dogs which set in said tubular spaces and lie within notches f in the side of the tablet rods. The inner ends of the keys set in notches f in the sides of the tablet rods and as any key is depressed at the outer end the tablet rod connected therewith is raised and the dog H, is carriedup. On the dogs ll, there are pins Z, and a long flexible pin L, made of wire, which is attached to the frame piece a, stands down by the side of the dog and back of the pin Z, and serves to keep the dog to its work on the ratchet pins on the wheels.

Extending out from the frame piece a are two brake springs, K and K, which bear, respectively, on the wheels D and D, and serve as a brake on each of said wheels. The wheels D and D are made of wood, preferably, and are loose on the shaft E. The primary wheel D, has a rabbet d on its side and the ratchet pins (Z are set in the vertical wall of that rabbet, and this wheel has a boss or hub d which keeps it away from the wheel D which has on its opposite side a thinner boss (Z for the same purpose. The pins (1 in the wheel D are on the side of the wheel facing the pins on the wheel D, and just below the plane of the horizontal wall of the rabbet d There is a notch h cut in the rabbet (Fat one point. The nose of the dog H rides on therabbet and can not come in contact with any of the pins (1' on the wheel D except when it falls into the notch 7L, there it will,-as it is moved up, come in contact with one of the pins d and move the wheels D one degree. The notch f, in the tablet rod F, in which the dog H, is held is longer than the dog, considerably, so that the rod F, may have a much longer traverse than the dog. The rod F has to move far enough to allow the tablet to appear and disappear and the tablet should be about an inch and a quarter in length; but, on the other hand, the wheels D, should not be moved but a short distance; hence the object of the long notch f and the holding of the dog in place without attaching it to the rod F.

Near the top of the tablet rod F, is a notch f, and extending from the reading bar a are springs J, which will fall into the notchesf when the tablet bar is lifted up, and when so in place the springs will hold the rods up until they are withdrawn from the notches.

On the top of the frame-piece a and held in place by the frame piece a is the releasing bar I, which is moved longitudinally by apin 0, on the lifting rod O, which is moved by the O-key 0, said pin working in a diagonal slot 2" in the said bar I. Along the under side of the bar I, are notches a, which embrace the springs J, and when the bar I, is moved by the action of the key 0, the springs J, will be pulled out of the notchesf, and the tablet rods F, will be free to drop.

At the lower end of the tablet rods there are notches f and at the back end of the drawer space thereis alaterally sliding bar M. When the drawer is shut this bar is pushed back and when the drawer is opened it is shoved forward by a spring m. lVhen this bar M, is shoved back it will enter the notches f of all the tablet rods that are down and it will set under the ends of any rods that are up. So when the drawer is shut none of the tablets that are down can be moved until the drawer is opened.

On each key, except the O-key, there is a pin 0, which, when the key is depressed at its outer end will be inserted between the ratchet pins on the wheel D, as seen in Fig. 3, and prevent the wheel being turned too far by any momentum that may be imparted to it. The brake spring K, of course, tends to prevent undue momentum, but its ofiice is to prevent the wheels turning by contact with other wheels and by jars, and the pin 0, serves to certainly prevent the wheels turning too far by the momentum they receive by the action of the keys.

In the construction shown in Figs. #1c and 5, the inner end ofthe key is not held from d ropping after the tablet rod is up, as in the other construction, but is provided with a spring 0 for throwing. itback as soon as released from pressure of the finger. To allow this action the notch f at the lower end of the tablet rod is made open at the lower end as seen in Fig. 10. lVhen this construction is used, the brake spring K, which acts upon the wheel D, may be omitted and a catch rod 0 be set into the key 0, directly above its pivot, as seen in Figs. a and 5. Then the key is depressed at its outer end the catch rod draws out of contact with the ratchet pins while the tablet rod is moving up into contact with the dog II, and when the key is released from pressure the catch rod 0 will be thrown back into place between the ratchet pins, and so when the tablet rod is released and allowed to drop and carry down the dog the backward action of the dog can not move the wheel backward.

In Fig. 5, a drawer catch P, is shown by dotted lines. The drawer catch is not on the key 0, but on the O-key, hence it is shown only by dotted lines, so as to illustrate its relative position. In Fig. 1, a top view of this catch P, is shown in full lines on the 0- key. The catch consists simply of a vertically moving bar, which is attached to the 0- key by a pin in a slot in the bar, so as to allow the key to move independent of the bar. WVhen the bar is raised by the action of the key it is drawn out of a notch in the side of the drawer and as the drawer opens the bar will rest on the top of the side of the drawer. A wire spring 19 may be applied to act upon the bar.
